A dental curing light is a piece of dental equipment that is used for polymerization of light cure resin based composites.[1] It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum. This light is delivered over a range of wavelengths and varies for each type of device. There are four basic types of dental curing lights; Tungsten halogen, light-emitting diode (LED), plasma arc curing (PAC), and laser. The two main dental curing lights are the halogen and LED.
